Gmail Spam Filtering seems to perform reasonably with the heterogeneous mix
of PGP and clear text email that I currently receive. I have noticed that
encrypted emails from new contacts occasionally take additional time to be
delivered. But I've got insufficient observations to disambiguate this from
the normal stochastic variation of gmail delivery times. Do we imagine that
the existing system only begins to fails once e2e traffic approaches some
If this is a case, what we need is a system for gradually adding new
cryptographic reputation signals as we approach that threshold.
One thing I like the about the cryptocurrency transaction idea is that it
adds a server readable cryptographic reputation signal to the message. The
emails would be constructed as message which is signed by sender key then
encrypted to recipient public key then signed by emails service's
cryptocurrency key. The third signature and a corresponding cryptocurrency
ledger transaction to enhanced deliverability in fully optional manner.
